Timezone handling is definitely an area where Coda will be improving in the future.
The current state of the world:
- There’s currently no doc-wide or per-column setting for default timezone. Each individually entered date or datetime is assumed to be in PST unless a timezone is specified explicitly (e.g., “Sept 20, 2018 15:00:00-05:00”).
- Calendar view will display events relative to the user’s local timezone, as reported by the browser.
As long as your date/datetime data is specified in PST or carries explicit timezone information, your calendar view should render nicely with localized event times for users in different timezones around the world. As an example, if I schedule an event at 9 am in PST, then a user in Rome would see that event on their calendar rendered at 6 pm. If that user in Rome then tells their browser they’re in California, they’ll see that event rendered at 9 am on their calendar.
We’d love to hear more specifics about how you’d like this stuff to work, so please keep detailed scenario-based feedback coming!
